WW 8 M1 BY and Patented Mar. 23, 1954 POWER-DRIVEN ROLLS FOR LUMBER AILERS I Glen Lee, John Day, :Oreg. v Application July 12, 1951, Serial No. 236,356

The present invention relates to improvements in lumber trailers and more particularly to a means provided for effecting rotation of one of the rolls of a lumber trailer whereby lumber can be easily loaded on or unloaded from a trailer. The primary object of this invention is to provide power driven rolls suitable for use on either lumber trailers or trucks or both, and which rolls may be driven either forward or backward to v facilitate either loading or unloading of such vehicles.

An object of the present invention resides in the provision of means driven by the power takeoff of a truck, the means being connected to the rearmost roll of a trailer for efiecting rotation thereof whereby loading and unloading of lumber can be facilitated.

A further object of the present invention resides in the provision of means driven by pressure supplied by the engine of a truck whereby the rear roll of the trailer can be rotated for aiding in the loading and unloading of a trailer.

Still another object of the present invention resides in the novel construction of the rearmost rollwhereby the same can be positively rotated and wherein the roll is constructed to effectively lubricate the bearing supports therefor. f

' Various other objects and advantages will become apparent from the detailed description to follow. The best forms in which I have contemplated applying my invention are clearly illustrated in the accompanying drawings, wherem: 1

Figure 1 is a side elevational view of a conventional trailer truck adapted for carrying lumber and to which the present invention is applied;

Figure 2 is a vertical longitudinal sectional view through a portion of the trailer of Figure 1 showing the first form of means for operating the rearmost roller, parts being broken away;

Figure 3 is a side elevational view of a portion 7 of the trailer truck, parts being shown in section for exposing the second form of meansfordriv-i ing the rearmost roller;

Figure 4 is a vertical transverse sectional view taken substantially along the plane of line -44 of Figure 3; and

Figure 5 is a detailsectional view through a portion of one of the rollers of the trailer.

Referring more particularly to the drawings;

wherein, like numerals designate like parts throughout, the numeral Ill'designates generally the truck, while the numeral l2 designates gen erally the lumber trailer for the truck." 'The first form of means for driving the rear/roll is designated generally bythe -numeral-l4 'and j-is 5 Claims. (Cl. 214-84) 2 best shown in Figure 2. The second form of means driving the rear roll isdesignated generally by the numeral l6 and is best shown in Figures 3 and 4.

Looking now at Figures 1 and 2, it will be seen that the truck and trailer l8 and are of conventional form, the frame l8 of the trailer being pivotally secured to the frame ,28 of the truck H) by means of the fifth wheel 22. The truck is supported on wheels 24 while the trailer has rear supporting wheels 26.

The frame I8 is comprised of longitudinal side members 28 and 30 joined by the angle irons 32 and 34 at each end. The side frame members 28 and 30 are also joined by a pair of channel iron members 36 and 38. Planking 48 covers the upper surface of the frame l8.

On top of the planking 40 is placed a plurality of pairs of angle irons 42, 44 which are disposed transversely of the trailer and have their ends joined by the bearing plates 48. The angle irons 42 have reduced size angle irons 50 secured in angular relation thereto whereby the inclined plates 52 can'be welded thereto. The rearmost angle iron 42 has an elongated inclined plate 54 secured to the angle iron 52 and the angle irons 32 and34. The plates 52 and 54 provide means for guiding the end portions 56 of pieces of lumber onto the rolls 58 and 60. The rolls 58 and 60 are rotatably journaled on the plates 48 in a manner to be more fully described here-i inafter. r t The first form of means l4 for driving'the rear roll 58 includes the provision of a pressure reservoir 62 which is connected to the engine whereby the same can be maintained at predetermined pressure. Air hoses 84 interconnect the reservoir 62 with a conventional air motor 65 which is mounted on the supporting plate 68 carried by the angle irons l8 and 72, thezangle irons 18 and 12 extending transversely-of the trailer andsupported by the lower portion 14 of the channel iron side members 28 and 38. The air motor 66 has a drive. shaft 16 extending therefrom.

The bracket 18 is secured to the channel iron transverse member 38 and has a plurality of gears 80, 82, 84 and 86 'rotatably carried thereby and interconnected. The gear 88 is connected to the shaft 16 for rotation thereby, the gear 86 being driven by the gear train. The gear is fixedly mounted on the shaft 88 which extends through the'channel iron'member 38 to the flexible coupling 90. The gear housing 92 is supported on the trailer and has'several gearings (not shown) whereby the shaft-94 connected to T OFFICE gaged in openings formed therein whereby oil on 5.
